This ones for everyone, just wanted to know if you start counting days in flowering the second you switch the lights or the first signs of flowering on the plant?
I always add 2 weeks to my "actual" flower time for pre flower. One excellent way to combat this though is 48 hours of darkness before switching to 12/12. No bullshit it knocks 1.5 weeks of flower time off most strains.
Yeah i've just been using 12/12 switch as day 1, and i've heard of leaving lights off for 2 days before flowering i just dont really like the idea of that haha
Some people leave a week or two out for 'pre flowers' so they can determine the sex, however, whether its male or female I personally go by the start of flowering as soon as I switch to 12/12
